Putnam Money Market Fund, as of September 30, 2008, annual
shareholder report

New accounting pronouncements

In June 2006, the Financial Accounting Standards Board (FASB)
issued Interpretation No. 48, Accounting for Uncertainty in
Income Taxes (the Interpretation). The Interpretation prescribes
a minimum threshold for financial statement recognition of the
benefit of a tax position taken or expected to be taken by a
filer in the filers tax return. Upon adoption, the Interpretation
did not have a material effect on the funds financial statements.
However, the conclusions regarding the Interpretation may be
subject to review and adjustment at a later date based on factors
including, but not limited to, further implementation guidance
expected from the FASB, and on going analysis of tax laws,
regulations and interpretations thereof. Each of the funds
federal tax returns for the prior three fiscal years remains
subject to examination by the Internal Revenue Service.

In September 2006, the FASB issued Statement of Financial
Accounting Standards No. 157, Fair Value Measurements (the
Standard). The Standard defines fair value, sets out a framework
for measuring fair value and expands disclosures about fair value
measurements. The Standard applies to fair value measurements
already required or permitted by existing standards.
The Standard is effective for fiscal years beginning after
November 15, 2007 and interim periods within those fiscal years.
Putnam Management does not believe the adoption of the Standard
will impact the amounts reported in the financial statements;
however, additional disclosures will be required about the inputs
used to develop the measurements of fair value.

In March 2008, Statement of Financial Accounting Standards No.
161, Disclosures about Derivative Instruments and Hedging
Activities (SFAS 161) an amendment of FASB Statement No. 133,
was issued and is effective for fiscal years beginning after
November 15, 2008. SFAS 161 requires enhanced disclosures about
how and why an entity uses derivative instruments and how
derivative instruments affect an entitys financial position.
Putnam Management is currently evaluating the impact the adoption
of SFAS 161 will have on the funds financial statement
disclosures.

In September 2008, FASB Staff Position FAS 133 1 and FIN 45 4,
Disclosures about Credit Derivatives and Certain Guarantees: An
Amendment of FASB Statement No. 133 and FASB Interpretation No.
45; and Clarification of the Effective Date of FASB Statement No.
161 (Amendment) was issued and is effective for annual and
interim reporting periods ending after November 15, 2008. The
Amendment requires enhanced disclosures regarding a funds credit
derivatives holdings and hybrid financial instruments containing
embedded credit derivatives. Management is currently evaluating
the impact the adoption of the Amendment will have on the funds
financial statement disclosures.

Report of Independent Registered Public Accounting Firm


To the Trustees and Shareholders of Putnam Money Market Fund:

In planning and performing our audit of the financial statements
of Putnam Money Market Fund ( the Fund ) as of and for the year
ended September 30, 2008, in accordance with the standards of the
Public Company Accounting Oversight Board (United States), we
considered the Funds internal control over financial reporting,
including control activities for safeguarding securities, as a
basis for designing our auditing procedures for the purpose of
expressing our opinion on the financial statements and to comply
with the requirements of Form N SAR, but not for the purpose of
expressing an opinion on the effectiveness of the Funds internal
control over financial reporting.  Accordingly, we do not express
an opinion on the effectiveness of the Funds internal control
over financial reporting.

The management of the Fund is responsible for establishing and
maintaining effective internal control over financial reporting.
In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and
related costs of controls.  A funds internal control over
financial reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles.  Such
internal control over financial reporting includes policies and
procedures that provide reasonable assurance regarding prevention
or timely detection of unauthorized acquisition, use or
disposition of a funds assets that could have a material effect
on the financial statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

A control deficiency exists when the design or operation of a
control does not allow management or employees, in the normal
course of performing their assigned functions, to prevent or
detect misstatements on a timely basis.  A significant deficiency
is a control deficiency, or combination of control deficiencies,
that adversely affects the funds ability to initiate, authorize,
record, process or report external financial data reliably in
accordance with generally accepted accounting principles such
that there is more than a remote likelihood that a misstatement
of the funds annual or interim financial statements that is more
than inconsequential will not be prevented or detected.  A
material weakness is a control deficiency, or combination of
control deficiencies, that results in more than a remote
likelihood that a material misstatement of the annual or interim
financial statements will not be prevented or detected.










Our consideration of the Funds internal control over financial
reporting was for the limited purpose described in the first
paragraph and would not necessarily disclose all deficiencies in
internal control over financial reporting that might be
significant deficiencies or material weaknesses under standards
established by the Public Company Accounting Oversight Board
(United States).  However, we noted no deficiencies in the Funds
internal control over financial reporting and its operation,
including controls for safeguarding securities, that we consider
to be material weaknesses as defined above as of September 30,
2008.

This report is intended solely for the information and use of
management and the Board of Trustees of Putnam Money Market Fund
and the Securities and Exchange Commission and is not intended to
be and should not be used by anyone other than these specified
parties.
